MACHINE FOR TURNING HUBS, TOOL-HANDLES, &c.

Specification of Letters Patent No. 11,777, dated October 10, 1854.

To all whom t may concern Be it known that I, SAMUEL CARPENTER, ofFlushing, in the county of Queens and State of New York, have invented anew and Improved Machine for Turning Hubs, Tool- Handles, Sac.; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the anneXed drawings, making a part ot this'specification,in which- Figure 1, is a plan or top view of my improved machine. Fig.2,' is a side View of ditto. Fig.A 3, is a side view of the pulley,which gives motion to the stuff, and through which pulley the staif isfed to the cutters. Fig. 4, is a side View of the cutter stock.

Similar letters of reference indicate corresponding parts in the severalgures.

This invention relates to a new and useful machine for turningv andboring hubs tool handles, and other articles ot a beaded and regularcurved form.

The nature of my invent-ion consists:

1st. In giving a rotary motion to the stuff to be turned and bored, byhaving the stuftI fed to the cutters through the center ot a pulleywhich is driven by a band wheel, said pulley communicating the rotarymotion to the stuit, and allowing it to be fed through its axis at theproper intervals'.

2d. My invention consists in the peculiar mechanism devised foroperating the cutters, bit or auger, and belt shipper. This mechanismwill be fully described hereafter.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, A, Figs. 1 and 2, represent two horizontal bed pieces, supported bysuitable standards, B, B. The above parts may be constructed of eitherwood or metal.

C, is a stationary head, secured to the bed pieces, A, A, by bolts, (a).On the upper part of the head, C, a pulley, D, is placed, said pulleyhaving its axis, (b) running in suitable bearings, (c), (o), in thehead, C. The axis, (Z9), of the pulley, D, has a square opening, (d),made longitudinally through, as shown in Fig. 3.

E, Figs. 1 and 2, is a movable and sliding head, which works on the bedpieces, A, A; and F, is a nut secured to the lower part of the head, E.

G, is a screw rod, which passes through the nut, F. The ends of thescrew rod, G, work in suitable bearings, (e), (e), one at each end ofthe bed pieces, A, A. The screw rod running parallel with the bedpieces. On one end of the screw rod, G, there are two pulleys, H. I. Oneof the pulleys, H, is attached permanently to the screw rod, and theother pulley, I, works loosely thereon, and has a hollow arm, J, with ascrew wheel, K, upon it, said screw wheel gearing into a horizontal wormwheel, L.

M, see Figs. 1, 2, and 3, is a transverse sliding bar, which works insuitable guides, (f), (f), see Figs. 1 and 2, on the upper part of thebed piece, A,A.

To the sliding bar, M, there is attached an upright, N, which forms acutter stock for a finishing chisel, O. To one side of the upright, N,there is attached by a pivot, g), a cutter stock, P, more particularlyshown in Fig. 4.

M', Fig. f1, is a spiral spring underneath the sliding bar, M.

The cutter or finishing chisel, O, has a cutting edge, made tocorrespond to the desired form of the articles to be turned. The cutteron the upper part of the stock, P,rep resented by Q, is merely a cuttingott tool, with a plain, narrow, beveled edge, as shown clearly in Figs.1 and 4.

R,is astationary cutter or gouge attached to the side of the head,.C,as` shown in Figs. 1 and 2.

S, is a bit or auger attached to the ends of a rod, T, which slides insuitablebearings on the upper part of a frame, U, on the bed pieces, A,A. Around the rod, T, there is a spiral spring, (h), the use of whichwill be hereafter shown. V, is a bent lever, having its fulcrum at (i),one end of this lever is attached to the outer end of the rod, T, andthe other end projects a short distance over the face of the worm wheel,L, see Fig. 1.

W, X, are two levers having the same fulcruln, 7'),-the outer ends ofthese levers also project over the faceof` the worm Wheel, L, seeFig. 1. The lever, W, is connected to the upright, N, of the slide, M,by a rod, (k), and the lever, X, is connected to the stock, P, by a rod,(Z), see Figs. 1 and 2.

On the face of the worm wheel, L, are three upright pins, (m), (n), (o),all of them are shown in Fig. 1.

Y, is a belt shipper attached to a lever, Z, said lever having itsfulcrum at (p), see

" lever, Z, in its proper position.

cuts or roughs o the corners of the stuff,

- worm wheel, L, and the pin, (m), bears -on the same shaft, C', as theband wheel,

Fig. 1, and (g), is an upright attached to the lever, Z, and having ahorizontal arm, (1"), which is directly in line with the hole, (d).-,inthe pulley, D.

Y, is a spring catch which secures the A, is a band wheel, by whichmotion is given the pulley, D; and B, B, are pulleys the pulleys, B,giving motion to the pulleys, H, I. 1

Operation: rlhe st-uff to be turned, is made of square form by previoussawing, and of such al size as to pass through the square hole, (d), inthe axis, (b), of the pulley, D, see Figs. 1, 2, and 3, the stuff beingrepresented by D. One end of the stuff isplaced within the axis, (b), ofthe pulley, D, and the opposite end is supported by a center point,(af), in the sliding head, E. Motion is then given the shaft,l C',andthe band wheel, A', gives a rotary motion to the pulley, D, by meansof a band, (b), and the pulley of course rotates the stu. The screw rod,G, also rotates at the same time, by means of a belt, (0), which at thistime, passes around the pulley, H, which is attached to the rod, G, seeFigs. 1 and Q. 'Ihe rotating of the screw rod, G, as the nutI fitsaround it, causes the stuff, D, to be moved through the hole, (d), inthe axis, (b), of the pulley, D, and the stationary cutter, R, attachedto thehead, C,

and the ends of the stuff, after passing' through the axis, Y(b), arequisite distance, comes in contact with the arm, (1"), and throws backthe belt shipper, Y, which of course, throws the belt, (0'), fromVthepulley, H, to the pulley, I. The screw, G, now ceases to rotate, andthe screw wheel, K, has a rotary motion, and gives motion t-o theagainst-one arm of the bent lever, Y, and thus throws the bit or auger,S, forward, andY into the ends of the stuff, D. The stuff, D', stillrotating, but not moving forward through the axis,`(? The sliding bar,M, is now moved by means 0f the pin, (n), coming in contact with the endof the lever, W', and the cutters are consequently made to act upon thestuff, the cutter, O,v cuts the wood in the desired form, while thecutter, Q, at this time, merely cuts a recess into the stuH to Yallowthe cutter, 0, to out clean at the end. The. pins, (m), (n), havingpassed the levers, V, W, the bit or auger,

S, is forced back to its original position by the spiral spring, (71,),and the cutter, 0,; is

forced back sufliciently to clear the stuft' by means of the spiralspring, M', underneath the slide, M. The pin, (n), now acts against theouter end of the lever, X, and forces forward the cutter, Q, the stock,P, of which works on the pivot, (g), and the finished article is cutolf, and the slide is forced back to its original position by thespring, M, and the belt shipper, Y, is thrown back, and the belt, (0'),is thrown upon the pulley, H, by means of a pin, (t), on the lever, X,striking a projection, (c), on the lever, Z, see Fig. 1'. At the nextoperation, the pin, (or), acts against the arm of the lever, V, thethree pins forming an equilateral triangle on the face of the wormwheel, L.

By the above machine, hubs for wagons, tool handles, and all articleshaving a regular curved form, may be turned with the greatest facility.The length of each article turned, will be equal, because the extremeend of the stuff acts upon the belt shipper, and shifts the belt, (0'),at equal length of the article to be turned, and articles of differentlengths may be turned by properly adjusting the arm, (r), so as to allowa greater or less length of stuff to pass through theY pulley, D, beforeacting against the arm, Y

I do not claim turning, boring, tapering andl shouldering handles eithercylindrical or conical by meansy of hollow cutters, tapering cutters,bits or drills,`as none of these devices are new; but

What I claim as my invention and desire to secure by Letters Patentisf 1. The use or employment of the pulley D so constructed and arrangedas to communicate a continuous rotary motion to the stuff to be turned,and to allow the same to be fed freely through its Iaxis at the properintervalssubstantially as described, and for the purposesspecilied.

2. The arrangement, and combination of the pulleys H, I, screw, and wormwheels K, L, levers W, X, V, and slide M, for the purpose of operatingthe cutters, O, Q andV .vpose of causing the turned articles toV be -cut0E from the stuft1 of equal length, as set SAMUELy CARPENTER. Witnesses:
